“Yes. It’s Zeyk. He and Nazik have moved here so that we can study him. He’s being very cooperative; she’s encouraging him. There might as well be some good that comes of it, she says. He doesn’t like his ability, you see. In him it doesn’t have much to do with computational tricks, although he’s better at that than most of us. But he can remember his past in extraordinary detail.”

“I think I remember hearing about this,” Sax said. The two women laughed, and startled, he joined in. “I’d like to see what you’re doing with him.”

“Sure. He’s down in Smadar’s lab. It’s interesting. They view vids from events that he witnessed, and ask him questions about the events, and he talks about what he remembers while they’ve got all the latest scans running on his brain.”

“Sounds very interesting.”

Ursula led him down to a long dimmed lab, in which some operating beds were occupied by subjects undergoing scans of one sort or another, colored images flickering on screens or holographically in the air; while other beds were empty, and somehow ominous.

After all the young native subjects, when they came to Zeyk he looked to Sax like a specimen of Homo habilis, whisked out of prehistory to be tested for mental capacity. He was wearing a helmet studded with contact points on its inner surface, and his white beard was damp, his eyes sunken and weary in bruise-colored, withered skin. Nazik sat on the other side of his bed, holding his hand in hers. Hovering in the air over a holograph next to her was a detailed three-dimensional transparent image of some part of Zeyk’s brain; through it colored light was flickering continuously, like heat lightning, creating patterns of green and red and blue and pale gold. On the screen by the bed jiggled images of a small tent settlement, after dark. A young woman, presumably the researcher Smadar, was asking questions.

“So the Ahad attacked the Fetah?”

“Yes. Or they were fighting, and my impression was that the Ahad started it. But someone was setting them on each other, I thought. Cutting slogans in the windows.”

“Did the Muslim Brotherhood often have internal conflicts this severe?”

“At that time they did. But why on that night, I don’t know. Someone set them on each other. It was as if everyone had suddenly gone crazy.”

Sax felt his stomach tighten. Then he felt chilled, as if the ventilation system had let in the air of the cold morning outside. The little tent town in the vids was Nicosia. They were talking about the night John Boone had been killed. Smadar was watching the vids, asking questions. Zeyk was being recorded. Now he looked at Sax, nodded a greeting. “Russell was there also.”

“Were you,” Smadar said, looking at Sax speculatively.

“Yes.”
